BTW was that a dual AMD or Intel btw? I think it's an Intel rig (based on the "12-cores vs 24-threads" and the fact that I don't think AMD has multithreaded CPUs (they seem to prefer sharing the FPU part (and sometimes the decoder) between 2 cores instead)). [ And the times are with "--enable-checking --enable-check-lisp-object-type". ] Sadly, the machines I use most of the time are pretty far from that, using low power net(book|top) CPUs, so bootstrapping takes more like half an hour (so I work hard to avoid bootstrapping).
